teraction characteristics and conception characteristics characteristics. The three important characteristics used to distinguish adjacent technology, such as multimedia technology, puter visualization technology immersion feature, whereby the VR provides a virtual world, so that the user can feel it is true in an objective world。 interactive features, requires that the user can use human familiar way, the entity in virtual environment observation and manipulation of concept。 concept characteristic, namely from qualitative and quantitative integrated environment for the perceptual and rational knowledge, thus the concept of novelty and germination. stages in the development of VR Technology The development of VR technology can be divided into three stages: nieen fifties to 70 time, VR is the preparatory stage。 at the beginning of the 8039。 s to mid 8039。 s, is a VR technology systematic, began to move out of the laboratory into practical application stage。 at the end of the 8039。 s to early 9039。 s, is the rapid development of VR technology stage. The first phase,50to 70 years, as the virtual reality the exploration stage of the United States in 1965 by Morton Heileg developed a motorcycle simulator called Sensorama, not only has a threedimensional video and stereo effect, can have a feeling of wind and streets smell1968, American puter scientist I1E1Sutherland at the Harvard University developed the first puting machine graphics driver helmet mounted display HMD and head position tracking system, bee the VR technology history an important milepost, virtual reality development laid the foundation. 中原工学院信息商务 学院毕业设计（论文）译文专用纸 第 8页 The second stage, the early 8039。 s to 80time metaphase, begin to form the basic concept of VR, started by the experiment into the practical stage, an important sign of which is that: in 1985 Michael Mc Greevy finished under the VIEW virtual reality system, equipped with a data glove and head tracker, provides gestures, language and other means of interaction, make VIEW be be worthy of the name of the virtual reality system, later to bee the development of virtual reality system structure of other panies such as VPL have been developed for the generation of virtual reality RB2 software and Data Glove data glove, for virtual reality provides development tools. The third stage, the late 8039。 s to early 9039。 s, as the virtual reality development virtual reality technology from laboratory experimental stage to market a practical stage, on the virtual reality technology research from the basic theory and system structure of steering application encountered specific problems. In the virtual reality system only a variety of interactive device is not enough, must also provide basic software support environment, user can facilitate the construction of virtual environment and virtual environment into the line of advanced interactive. In order to make the VR technology has been widely used, so it is necessary to analyze the system of virtual reality software support environment, system structure, such as a Dialogue system, puts forward a kind of based on event driven drive users export management system ( UMIS ), can be in the range of munication software system structure, solves the problem of the dynamic flexibility of virtual reality, advanced software support ring Environmental development. In order to meet the needs of virtual reality on the putational plexity of the few is infinite, t。
